Answer:

Step-by-step explanation:

Using the rule of exponents

$\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$ , then

$\frac{2^{12} }{2^{3} }$ = $2^{(12-3)}$ = $2^{9}$

Island A is 150 miles from island B. A ship captain travels 240 miles from island A and then finds that he is off course and 200

Stells [14]

We know that
Applying the law of cosines:

c² = a² + b² - 2abcos(C) 
where: 
a,b and c are sides of the triangle and C is the angle opposite side c 

that is 
150² = 240² + 200² - 2(240)(200)cos(C) 

solve for C 

22,500 = 57,600 + 40,000 - 96,000cos(C) 
22,500-57,600-40,000 = -96,000cos(C)
-75,100=-96,000cos (C)
cos (C)=0.7822916
C=arc cos(0.7822916)--------> C=38.53°°

hence, 
he should turn in the direction of island b by
180 - 38.53 = 141.47 degrees

A system of linear equations contains two equations with negative reciprocal

aleksandrvk [35]

let's recall that perpendicular lines have negative reciprocal slopes, so say for a line with a slope of a/b

$\bf \stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}} {\stackrel{slope}{\cfrac{a}{b}}\qquad \qquad \qquad \stackrel{reciprocal}{\cfrac{b}{a}}\qquad \stackrel{negative~reciprocal}{-\cfrac{b}{a}}}$

a perpendicular one will be -b/a.

what does that mean? well, that the lines are perpendicular of course, they meet at a 90° angle, and two straight lines meeting at 90° can only meet once.

since a solution to a system of equations is where the graph meet, and these two meet perpendicularly once, then that means only one solution.
